The free end of the actuating lever 36 is provided with a cam roller 51which rides upon the circular cam 52. A rotative motion is imparted to the cam 52 by the operative connection of the shaft 53, upon which the cam is mounted, with a driveshaft 54;

through a sprocket and chain connection 55.

A spring 57 has one end connected to a lug 46 and the other end fixed to astationary arm '58 so as to normally rotate the shaft 42 in'a clockwise direction (Fig. 2). Disposed beneath the lug 46 and arranged to engage therewith, so as to hold the lug and its cooperating parts in a predetermined position, is a latch 59 which is movable'vertically in bearings 60 and 61 and which is normally moved upwardly by a spring 62, which is disposed concentric with the latch 59 between the bearings 61 and the collar63, the latter being pinned to the latch. A releasing cam lever64 is pivotally mounted upon a shaft 65 andhas a cam roller 66 which rides upon a rotating cam 67 provided with a raised portion 68, the cam 67 being mounted upon and fixed to the shaft 54. The forked arm 69 is keyed tothe shaft 65 and arranged to strad-' die the latch 59 so that the arcuate shaped endsthereof rest upon a collar 63.

, The material transferring mechanism con-v sistsof a transfer arm 70 which has an artij cle receiving and retaining unit 71 carried at 7 7' and provided at the other end with a cam roller 78 which is disposed in engagenism a rockin ment witha rocking cam 79, the latter' being mounted upon the shaft 54. By this mechamovement is imparted to the transfer arm The rocking cam79 is so formed in its general contour thatinterinit tent rocking movements are imparted to the transfer arm and the transfer arm is held at restin' predetermined positions for a purpose hereinafter described.

A lateral movement is imparted to the transfer arm 70 by a rocking movement of a bell crank cam lever 81 which is pivotally mounted at 82 and has one end forked so as to straddle a collar 83, which is mounted upon the shaft 7 2, and operatively connected thereto by inwardly extending pins 84. The

other end of the lever 81 has rotatably carried thereby a cam roller 85 arranged to ride upon a peripheral edge of a cam 86 which is mounted upon the shaft 54. The general contour of the cams 79 and 86 will be hereinafter described. 1

'The article receiving and retaining unit 71 consists of a chuck 87 having a longitudinally extending aperture 88, the inner end thereof being shaped to conformto the article of manufacture, which "in the present instance is hexagonal in general contour. A bearing 89 is disposed in the outer end of the transfer arm 7 0, for rotatably receiving the chuck 87 when held in its outermost position; that is, toward the Work, by a resilient spring member 90 and is provided with spaced stop members 91 which are arranged toengage with stop pins 92 disposed in spaced positions in the chuck 87' for holding the chuck against rotation when in the innermost position. A knockout plunger 93 is disposed in the aperture'88 for moving the part, or article of manufacture, out of the aperture when the plunger 93 is moved inwardly due to its engagementwith a knockout arm 94 against the tension of a spring 95. The plunger 93 is limitedin its outer movement by a pin 96 which is-carried by the chuck 87. The knock out arm- 94 is adjustably' carried by 'a stop arm 97 which is for a' purpose hereinafter described."

A'cam' plate 98 whichis arcuate shaped in general contour is rigidly mounted upon an upright frame portion 100 and has one end disposed adjacent a work receiving and rotating'unit 101.""Apertures 102 and'103 are provided in .cam'plate 98 for receiving spring pressed collars 104 and 105 respectively which are normally held within the aperturesso thattheir-outer surfaces will be flush with the outer surface of the 'cam plate 98. The collar 104 is provided with an aperture 106 arranged to receive a countersinking tool' 107 which is secured'to the adjacent end of the driven shaft 31, while the collar 105 isp'rovided with an aperture 108 arranged to receive a tapping tool 109. The tool 109 is disposed inuthe outer end of the spindle 110 which is movable longitudinally in and rotatable with a casing 111. The connection between the spindle 110 and the casing 111 consists of spaced spherical or ball members 112, {which are held against movement relative to each other by a collar 113 provided with'spaced'apertures adapted to receive the spherical members, and which are receivable in spaced longitudinally extending grooves 114 in the casing 111 and spaced longitudinally extending grooves'llh in the spindle 110, these grooves being arcuate shaped in cross section. Casing 111 is rotatably disposed in a bearing 116 in the upright frame portion 110 and is mounted upon the adjacent end of the stop shaft 28.

* Theapparatu s showniinFigf8, which is effective prior to the performance-of the ad ditional operations upon the article, consists of aturret 140, which is actuated intermittently by a power means (not shown), and which is adapted to'be moved relative to the rotatingwunit 101 to perform its desired op erations; A stop member 141 'is carried by theturret 140 and is adapted to be disposed ingeneral alignment with therotating unit 101 so as to limit the'movement of the stock of material as it is moved forwardly therethrough; A centering tool142 is carried by the turret 140 and'is adapted to be disposed in engagement with theend of the material in the rotating unit 101 so-as to provide, a center for a drilling tool 143'whieh'is also carried by theturret 140 and arranged to drill anopening in'the end ofthe material. A slotting tool 144 is also carried by thetur ret and is operatively connected-to the power means (notshowh), for cutting the slot-in the end of the material;

From the foregoing description of the variousparts of-the apparatus, the operation,

7 thereof will be more clearly understood. After the'material-hasbeen moved forwardly, the predetermined distance governed by the stop member 141, received the centeringoperation with the centering tool"142, and re= ceived the drilling and slotting operations by the drilling too1143-and the slotting tool 3 144 respectively, the portion of the" material free of the revolving unit 101 is served therefrom. As the portions are severed fromthe material by a cutting tool'f117, the transfer arm is positioned adjacent the rotating unit 101 so that the'ap'erture 88 or the receiving unit 71 would be'in general alignment with the material for'receiving theseve'r'ed portions. The unit 71, 'while in thisposi tion, is free to rotate with the materialand in this manner the unit isallowed'to receive the end of the material before it is severed from the main body thereof.

After the portion or article ,is'severed,fa counterclockwise motion is imparted to the transfer arm 70 (Fig.4), thus movingthe article along the cam plate 98 to a'position in engagement with the jcollar '104 adjacent the aperture 106. Duringl the movement of the article into this position the engagement thereof with the cam plate 98 forces the articlefinto the chuck 87 so that the-circular, reduced portion of the article willbe received in the circular portion of the aperture. 88 and the hexagonal portion" of the article will be received in the hexagonal portion of the aperture 88 of the chuck 87 This swinging movement of the transfer arm 70 is brought about by the roller 78 of the rocking cam lever 76 riding upon the lifting por tion 1180f the-cam 79, thus moving the lever 76 above its pivot'77 and rotating the shaft 72in ai -counterclockwise" direction due tothe.

70 and unit 71 will'beheldagainst a'la'teral swinging movement at this position while the roller 78 rides upon-the cam"surface"119. However, during the rest of the transferarm against a lateral swingingmovement,anim ward movement is imparted thereto l so as to move the article into operative. engage ment with the countersinking tool 107 and to move the spring pressed :collar 104 in-f wardly. The purpose of thespring pressed collar 104 is to hold the stop pins 92 into enlgagement with the stop members 91 and thus hold the chuck, against rotation; This. inward movement of the transfer arm, togeth er with the cooperatingpartsfor movingthe article into engagement with theicounten when rotated, moves theicam roller'85 up wardly over the lifting surface-120, thus swinging the lever81 about its pivot 82land moving the shaft 72 together with'the trans fer arm 70 inwardly. The countersinking tool 107 is continuouslyrotated casheretofore described. Y The article is then moved away from the countersinking member 107 whilethe trans; fer arm, and thei cooperating parts for-hold" ing. the article, remain in the rest position against swinging movement during the movement of the roller :85 over the cam sur; face'121 of th'ecam 86; The exposed surface of the article is againfldisposedhushwith the engaging surface' of the cami'98 and is next moved along the engaging surface and into engagement with thecollar105adjacent they aperture 108.v This movement. isim parted to the article by the continued rotation of the cam? 9 causing the camroller'l7'8 n to ride up the lifting surface 122 tothe cam surface 123 and by this movement afurther rocking 'movement is imparted to the lever 76 about its pivot 77'soaslto rock the shaft 72and the transfer arm 70 in a counterclocks 1 -5 1 Q I wise direction. The. article is held against swinging movement at thisposition but is moved inwardly into engagement "with' the' tapping tool 109 during the movement of the roller 85 over the cam surfa'ce 124 of the cam'86 a Prior to the engagement of the article with the tapping tool 109, the cam lever 36*is actuated due to the engagement of the cam rollat 51 with the lifting portion 125 of'theearn 1'25 52. so as tomove the clutch member 30'into operative engagement with'the clutch socket 27, thus operatively connectingfthej stub slraft' 28, withthe power :means'; ('not"shown)", 7

through the driven sleeve17 and rotating I30 thecasing 111 (Figs. 2. and 6). A rotation of the casing 111 will impart a rotative movement to the spindle 110 due to the operative engagement therewith through the spherical members 112 thus impartinga rotative movement to thetapping tool 109. This rotation of .the tapping tool 109 and its cooperating rotating members is in a counterclockwise direction, thus causingthe tapping tool-i109 to cut threads in the article. This operative engagement of the spindle 110 with the casing 111 allows the spindle to move relative to the casing so that the tapping tool 109 may move relative to the article as it is drawn therein by the tapping thereof. When the tapping tool has moved a predetermined distance relative to the article, the releasing cam lever 64 will be actuated during the movement of the cam roller 66 over the raised portion 68- of the cam 67 thus moving the latch 59 downwardly against the tension of the spring 62 and releasing the lug 46, allowing the spring 57 together with the spring 43 to rotatethe outer sleeve 37, the inner sleeve 41 and the shaft 42, thus moving the clutch member 30 out of engagement with the clutch socket 26 so as to operatively connect the stub shaft 28 with the driven sleeve 20.

The driven sleeve 20, due to its operative connection with the drive sleeve 17, through the gears 19, 35 and 32, the shaft 31 and the gears 33 and 25, will be rotated in a clockwise direction, thus imparting a similar rotative movement to the tapping tool 109 through the casing 111 and the spindle 115. During this movement of the tapping tool 109 in a clockwise directionya spring 126 which is disposed concentric with the spindle 110 will move the tapping tool out of the article as it is freed by the threaded connec tion. During this outer movement of the tapping tool 109, the cam roller 85 is moving over the cam surface 127 of the cam 86, thus gradually moving the article outwardly. After the article is free from the tap ping tool 109 and before the transfer arm is again moved into the receiving position, the cam roller 85 is allowed to pass overwthe cam surface 128 of the cam 86, thus moving the transfer arm so that the knockout plunger 93 will engage with the knockout arm 94, thus moving the plunger relative to the clutch 87 so as to force the article therefrom and allow the article to drop into the chute 129 where it is directed into a receptacle (not shown);

The transfer arm 70 and the unit 71 are then moved into the receiving positioned jacent the rotating unit 101 as the camroller 78 rides over the cam surface1307of the cam 79 and the cam roller 85 ride-s overthe cam surface 131 of thecam 86. The chuck 87 is held in its outwardly, rotatable posit ion as it is moved in to receive the next portion which is to be severed from the material during the movement of the cam roller 85 over the-cam surface 132 ofthe cam 86. During theoperation of this apparatus the chuck 87 is moved in to receive the article, which is severed from the material, and allowed to rotate during the severing operation, after which it is moved with the article along the outer surface of the. cam 98 where the article is forced more firmly into the chuck and the chuck'ismoved relative to the transfer arm-70 so as to move the stop pins 92 adjacent thestop members91 for locking the clutch 87 against rotative movement. In this manner the article is held against rotation as it is moved with the spring pressed collar 104 to receive the countersinking operation andsubsequently moved into engagement with the tapping member 109 for the tapping operation. The, various movements imparted to the article are effected by therotation of the cams .7 9 and 86 for actuating, at predetermined periods of time, the mechanism for operatively connecting these cams with the transfer arm. Furthermore, adjustable stop members (Fig. 4) are provided for assuring correct positions of the transfer arm 70. An adjustable stop 133 is carried by thetransfer arm 70 and arranged to engage with the stationary stop plate 134 for aligning the aperture 88 of the chuck 87 with the material in the rotating unit 101.

An adjustable stop member 135 is carried by the transfer arm 70 and arranged to engage with the stop arm 97 for aligning the article in the chuck 87 with the aperture 106 in the collar 104, and a stop member 136 is adj ustably carried by the transfer arm 70 and arranged to engage with thestop arm 97 for aligning the article in the chuck 87 with the aperture 108 in the collar 105.

In Fig. 9 the perspective view of the article 137is shown illustrating, the countersunk portion at 138 and a tapped opening at 139. These operationsare completed with the apparatus subsequent .to the other forming operations, while these other forming operations are being made upon the body of material in therotating unit 101 so that the next article will be readyto lee-severed from the material when the chuck 87 is disposed in engagementtherewith. v
